A rectangle has a vertex on the origin. If the rectangle is reflected over the y axis, then reflected over the x axis, and then translated 4 units up, where will this vertex be located?
(0, 4) (NOTE: this will be true no matter which quadrant you originally drew the rectangle in)
The following points are on a line: (4, 2) (4, 3) (4, 4) Is the line a function? Why or why not? You must correctly answer why or why not to get credit for this question.
no, because for the value x = 4 there is more than one possible y value

A triangle has the following dimensions: 4 cm, 5cm, 8cm Is it a right triangle? Why or why not? Note: to earn the points for this question, you must explain why or why not.
No because 4 squared plus 5 squared does not equal 8 squared.
